This library provides an easy way to control the BMP384 pressure sensor. It is a very precise sensor, allowing down to 1/64 Pa pressure resolution, plus a built-in filter to reduce noise. That's sufficient to measure the difference in pressure of raising/lowering the sensor by less than an inch!
The sensor also includes a temperature sensor, however it's not really intended for measuring air temperature; its main purpose is to compensate the pressure measurements. The measured temperature is usually a few degrees above ambient, and depends on things like the PCB temperature, sensor element, and even the I2C/SPI clock speed!
This library implements Bosch's BMP5 API in an Arduino-friendly way. All functions return error codes to indicate the result of each operation, where BMP5_OK (0) indicates success. The examples demonstrate basic ways of handling these errors, but error checking can be omitted to reduce code clutter if desired.
